jsonp proxy web app I can install?

Question

After getting stuck trying to access another domain with ajax I discovered I'll need to use jsonp. However the web service I'm using doesn't provide jsonp output. No problem, I can write something simple on my own webserver that will wrap the output of their thing with jsonp. However before I reinvent the wheel, is there some exisiting programme that will do this for me?
